Question

Go-live for a public integration when every customer uses their own Docusign account

am building a multi-tenant SaaS product and I want to make sure I pick the correct integration type before I promote my integration key.

Setup:
- One integration key, eSignature REST API, Authorization Code Grant, confidential client
- Each customer connects THEIR OWN existing Docusign account via OAuth consent
- Envelopes are created in, sent from, and billed to that customer's account
- No reselling, no billing through my company, no embedded signing ceremony in my UI

What the docs say, as I read them: "private custom integration" is for customers building an app for their own use, while "public integration" is for apps used by multiple Docusign customers and requires Docusign Partner Program membership to go live.

My questions:
1. Does my setup count as a public integration, or does private custom cover it, given that every account involved belongs to the customer and not to me?
2. If it is public, is Partner Program membership enforced at go-live even when there is no reselling and no embedding?
3. If membership is not an option for a company of my size, is there any supported path for this model, or is the answer simply no?

Any pointer to the authoritative doc section would be appreciated.

Hi ​@resolvR,

Please find below the answers to your inquiries.

1. Does my setup count as a public integration, or does private custom cover it, given that every account involved belongs to the customer and not to me?

Your setup is considered a Public integration. Your app is using a single Integration Key that multiple separate Docusign customers authorize against. "Private custom integration" is intended for internal use by your employees.

2. If it is public, is Partner Program membership enforced at go-live even when there is no reselling and no embedding?

Yes, partner Program membership is required to launch a public integration. This still applies even when there is no reselling or embedded signing.

3. If membership is not an option for a company of my size, is there any supported path for this model, or is the answer simply no?

The supported alternative is the "Bring Your Own Key" (BYOK) model. Instead of providing one centralized Integration Key, you require each of your SaaS customers to generate their own IK in their Docusign account (which they classify as a "Private custom integration"). They would then paste their unique IK and Secret into their tenant settings within your application.
